IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 202,622, dated April16, 1878; application filed July 27, 1876.

To all whom it may concern:

Be it known that l, JOSEPH A. WOODMAN- SEE, of New Vienna, Clintoncounty, Ohio, have invented an Improved Oar-Ooupling, of which thefollowing is a specification:

Figures 1 and 2 are vertical longitudinal sections of a couplingembodying my invention in the opened and closed conditions,respectively. Fig. 3 is an end view. Fig. 4 is a top view.

A represents the draw-head, having the customary mouth or muzzle a, toreceive the link, and vertical hole a, for the coupling pin or bolt B.The coupling-bolt B has a T-head, b, which travels up and down in guidesO.

A standard, D, which rises from the head A, afl'ords journal-bearings Efor trigger F, whose counter-arm f constitutes the lower member ofatoggle, fG, whose upper member, G, is pivoted to the standard at g, andto a sliding catch, H, at h, which catch plays in a horizontal slot, a.,in the top of the head.

Accidental escape of the boltB from the head is prevented by a block, K,whose removal enables the bolt to be unshipped when necessary.

A pin, L, inserted in a hole, I, in the guides, serves to hold the boltB to its elevated 1 position independently of the trigger, when desired.

The operation is as follows: The draw-head is set to receive the link Iof the opposing car by elevating the bolt B and engaging the catch Hunder the bolt-head, as in Fig. 1. This action advances the lower end ofthe trigger F, as seen in said figure. The link I, now approaching,pushes back the lower end of trigger F. toggle f G, and retracts thecatch H, so as to liberate the bolt B, and to permit it to drop into andlock the link, as in Fig. 2.

The inner extremity of the locked link being held down by the shoulderor projection J of the interior of the head, the link is thereby held ina horizontal position, adapted to readily engage with the muzzle of anopposing car.

I claim as new and of my invention The coupling herein described,consisting of T-headed bolt B 1), standard D, guides O G, catch H,toggle G j, and trigger F.

In testimony of which invention I hereunto set my hand.
